Here we need to complete the table.
00:02
So first we have the solution a, then we are given with the solution b.
00:07
And then we need to tell whether that both will form the precipitate after the reaction.
00:12
And we need to tell the empirical formula for the precipitate.
00:17
Now here the solution a is iron 2 bromide, that is f, b, r2, aquas.
00:24
And here we have the ammonium sulfide that is nh4 twice.
00:30
Here we have equis.
00:32
Now here the reaction is f e s solid plus 2 nh 4 br so yes it forms the precipitate and empirical formula is fes so this is the first case moving to the second in the second we have sodium sulfate that is n a 2 so4 plus solution b is the lead to nitrate that is p b n o3 twice so here's the reaction is p b, so4, this will be formed as precipitate and 2 n -a -n -o -3.
01:07
So here we have yes and the empirical formula for the precipitate is p -b -s -o -4.
01:13
Now third one, iron -2 iodide...
